This invention relates to improvements in means for supporting, aligning and guiding a plurality of superimposed strips of paper, and means for supportin g in interleaved relationship with E6 the strips of paper, sheets of carbon paper, and

for utilizing all parts of the carbon sheets.

The invention has for its object the provision, in connection with an apparatus for supporting iii) a plurality of strips of paper, means for adjust ably supporting a plurality of sheets of carbon paper interleaved between the strips of paper.

It is an object of the invention to provide, in connection with -a typewriter, means for supporting a plural per fed to the typew ably supporting a p ity of superimposed strips of pariter, and means for adjustlurality of sheets of carbon paper interleaved between the strips of paper so that the sheets of carbon paper may be adjusted that the type of the typewriter will not strike upon the same line at all times.

In other words,

the type may strike upon that part of the carbon sheets between lines formerly used.

It is also an object of the invention to provide, in connection with a typewriter, a frame for supporting a plurality of superimposed strips of pa per adapted to be fed through the typewriter and by the typewriter, and to provide on this frame adjustable means i bon paper, and means to adjust or supporting sheets of carthe sheets of carbon paper with relation to the supporting means.

Figure 12 shows the front face of the carbon supporting plate, with means thereon for adjusting the position of the carbon sheets with re- 30 lation to the plate.

Figure 13 shows the back face of the carbon supporting plate, with means thereon for adjustably supporting the plate on the supporting chain.

Figure 14 shows the carbon sheets supported 35 in their lower position on the carbon supporting plate,

, upper ends by means of a cross bar i, and at their lower ends by means of a cross bar 5. These two cross bars are braced by means of braces ii, which are riveted by means of rivets i to the cross bars and to each other by means of a rivet 8., The lower end of the frame is provided with brackets t, by which the side bars operatively connects the lower sprockets l I to another pair of sprockets I3 located on the upper shaft l4, rotatably mounted on the upper end of the frame upon two bars I 5, each attached to one of the side bars by screws, not shown. Each shaft has thereon a pair of sprockets connected by means of the sprocket chains l2. The upper ends of these bars l5 are connected by means of a rod I 6.,

On the upper end of the frame and attached to the side bars is a guide plate II. This plate is attached to the side bars by means of rivets l8, and has adjacent each 'end thereof a slot l9 adapted to receive one end of a guide pin 20, adjustably supported in the slot by means of a screw 2| (Figure 4). adjusted to and from eachother, and serve to guide strips of paper 22 as they pass over a drum 23 mounted on the shaft l4.

Supported on the front of the frame and by the side bars thereof, is a carbon supporting plate 24. This plate engages the side bars at each end, and has struck up therefrom tongues 25, which fit behind part of the side bars for guiding the plate as it moves up. and down on the .frame. The frame is U-shaped, with the arms thereof projecting toward-each other, and it is the front arms of these side bars that are engaged by the carbon supporting plate and thetongues struck up therefrom.

This plate is adjlistably attached to the chains 82 by means of pins 26. There are two of these pins, one attached to each end of a flat spring 27, attached intermediate its ends to the plate by means of rivets 28 (Figure 10). The plate is provided with holes 2611 to receive the free ends of these pins. These pins pass through links of the chains for supporting the plate on the chains. Each pin is supported at one end by the flat spring, while its other end is supported by the plate when the plate is supported on the chains. The chains are held in close engagement with the plate by. means of loops 29. In the present instance there are two loops for each end of the flat spring. These loops prevent the chain from pulling the pins out of the'holes so there is no danger of the carbon supporting plate being accidentally released from Adjacent each end of the plate 24 is a U- shaped slot 30 (Figures 12 and 13). The arms.

of these slots project away from the ends of the plate so that the arms of one slot project toward the arms of the other slot and are parallel therewith. On the front side of the plate 24 is a spring strip 3|, which has attached to each end a pin am. The parts of these pins on one side of the spring strip are adapted to support a plurality of sheets of carbon paper interleaved between strips of paper, while the parts of the pins projecting on the other side of the spring strip serve 'to engage the plate 24 within the slots 30 to hold the spring strip in the slots in adjusted position with relation to the plate. By

this means the carbon paper can be so adjusted as to cause the type to strike the portion of the unused carbon sheets between the lines previously struck. The parts of the pins projecting through the slots are indicated by the These pins may be.

writer.

numeral 32, and have thereon washers 33 which serve to hold the pins and the spring strip against the plate, but permit a free movement in relation thereto.

The pins 3la. have thereon a plurality of circular notches 34 adapted to receive a member, not shown, for holding the carbon sheets on the pins. also provided with small pins 35 to prevent the carbon sheets from slipping off of the pins 3| a in the event no other instrumentality is used for that purpose.

At the back side of the frame is a paper feed plate 36, which is attached to the sprocket chains I 2, as by the bolts 36a. The feed plate 36' has at each end, on the upper edge thereof, a bracket 31 (Figures 4 to 8 inclusive). These brackets support a guide rod 38 by means of screws 39 extending through the brackets into the ends of the rod. On each end of the rod, adjacent a bracket, is a guiding disc 40 adjusted with relation to the rod by means of a set screw 4|. These discs are spaced according to the width of the paper being used on the apparatus. The distance these discs are apart also corresponds to the distance the pins 20 are apart.

The feed plate 36 also has on its lower edge, at each end, a bracket 42 to which is attached one end of an arm 43 by means of bolts 44. The upper end of each arm 43 has a stop 45 adapted to engage the upper edge of the feed plate. To the stop ends of the arms 43 is attached an angle iron 46, which has thereon aligning and feeding pins 41 adapted to pass through holes in the strips of paper and through holes provided therefor in the upper edge of the feed plate. The angle iron is urged toward the feed plate by means of a spring 48 connected at one end to the angle iron and at its other end to the rod 38.

There is also provided on the feed plate intermediate its upper edges and between its ends, brackets 49 which support a guide rod 59. This The extreme outer ends of these pins are guide rod serves to hold the strips of paper against Y the feed plate. This rod also cooperates with the rod 38 in holding the strips of paper in proper position when the aligning and feeding pins are withdrawn from the holes in the strips of paper.

The strips of paper are fed over the drum at the top of the frame from a pile of paper 55, located on some suitable support behind the type- Each strip of paper is divided by means of cross perforations 52, into sheets of sufiicient size for the desired use (Figure 1). Adjacent the upper edge of each sheet of the strip are holes 53 for receiving the pins 41. The carbon sheets are indicated by the numeral 54 and may be divided, as shown in Figures 9, 14 and 15 into narrow strips bymeans of cross perforations 55. These narrow strips are indicated by the numeral 56, the width of which may be varied to suit the extent of the carbon sheet to be used. After any one of these narrow strips has been so used that it has become worthless it maybe torn off.

The carbon sheets thus become shorter, and in order to use the other part of the sheet it is necessary to lower the carbon supporting plate on the chains. This is doneby withdrawing the pins 26 from the chains so that the plate may be slipped down, after which the pins may be forced to :engage anotherlink in the chain, whereby the plate is again supported in its desired position. When another of these narrow strips of carbon is used it is torn off andthe carbon sheet. Each carbon sheet is supported bon sheets relative to said plate by minute graby means of a narrow strip 51 composed of some suitable material. Usually this strip is made of some fibrous material, and has in each end a hole 58 adapted to'receive one of the pins Ma.

The lower end of each side bar is provided with a rubber stop disc 59 engaged by the paper feed plate when it is in its lowest position, and

when the carbon supporting plate. is in its uppermost position. On one of the side bars without the frame is a spring housing 60 (Figure 11) which has therein a coil spring 6| attached at one end at the "point 62 to the upper shaft l4, and atits other end at the point 63 to the spring housing 60. I

By adjusting the spring strip 3| on the plate 24 the point at which the type engages the carbon sheets may be changed so that the whole of the carbon sheet may be used. By varying the position of the plate Mon the chains the whole length of the carbon sheet may be varied. When a long sheet is used this plate is attached to the chain near the upper end of the frame while the on the chain a greater distance from the top of the frame, this distance depending upon the length of the carbon sheet. When the carbon sheets have been used and the lower narrow strips thereof tornoif, this plate 24 is lowered so that unused parts of the carbon sheets may be used.

By means of applicants apparatus every available part of the carbon sheet is used, thereby avoiding waste and lengthening the life of the carbon sheets and increasing the efficiency of the writing.
